Description

technical field

[0001] The invention relates to a combustion engine, in particular to a general-purpose high-speed engine. Background technique

[0002] General-purpose small gasoline engine is a kind of motor tool equipment, referred to as general machine, referring to gasoline engines other than those used for vehicles and special purposes, and its rated power is generally below 30kW. It is mainly used as supporting power for agricultural and forestry plant protection machinery, small agricultural machinery, garden machinery, generator sets, construction machinery, outboard machinery, etc. Because of its small size, light weight, low price, and convenient use, the general-purpose small gasoline engine occupies an important position in various machine tools. Especially among the knapsack machines, the general-purpose small gasoline engine is the only supporting power. The general-purpose small gasoline engine is the same as the general internal combustion engine, has a ba...
